Answer:

408

Step-by-step explanation:

You would set up a proportion of 1/12 = 34/x. You would do the butterfly method and get 1x=408. Then divide 408 by 1 to get 408.

Answer:

408

Step-by-step explanation:

You see the rate is one out of twelve(1/12)

So if 1 now equals 34 (ALWAYS KEEP THE FRACTIONS BALANCED, WHAT YOU DO TO ONE SIDE YOU MUST DO TO THE OTHER)

so to get 1 to 34 you multiplied by 34. So do the same to 12 to get your total number or surveyed students.

Hope I helped!

2 Select the correct answer. What is the inverse of function ? F(x)=10/9x+11 A.f-1(x)=9x-99/10 B.f-1(x)=9/10x+11 C.f-1(x)=9x+11/
Lilit [14]

Consider f(x)=y.

\begin{gathered} f(x)=y \\ x=f^{-1}(y) \end{gathered}

Simplify the equation f(x)=y to obtain the value of x in terms of y.

\begin{gathered} f(x)=y \\ \frac{10}{9}x+11=y \\ \frac{10}{9}x=y-11 \\ 10x=9y-99 \\ x=\frac{9y-99}{10} \end{gathered}

So inverse of function is,

f^{-1}(x)=\frac{9y-99}{10}

Correct nswer is A part.

2x -3y=4:(2,) fill the other coordinates
JulsSmile [24]

Answer:

x = 2 + 1.5y

Step-by-step explanation:

Simplifying

<em>2x + -3y = 4</em>

Solving

<em>2x + -3y = 4</em>

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3y' to each side of the equation.

<em>2x + -3y + 3y = 4 + 3y</em>

Combine like terms: -3y + 3y = 0

<em>2x + 0 = 4 + 3y</em>

<em>2x = 4 + 3y</em>

Divide each side by '2'.

<em>x = 2 + 1.5y</em>

Simplifying

<em>x = 2 + 1.5y</em>

  106°

Step-by-step explanation:

The intercepted arc is double the measure of the inscribed angle intercepting it. Each of the angles V and Y is 53°, so arc WX is 2×53° = 106°.
